Homework Equations
The Attempt at a Solution
my answer was {[itex] x = {\frac {1}{2^n} : n \in ℤ } [/itex]}
but my books was
{[itex] x = {{2^n} : n \in ℤ } [/itex]}
I understand both answers to be true. But would my answer be valid say, on a test or something. Is one of these preferred over the other?
